Be it known that we, CHARLES C. WORTH- INGTON, a'resident of Dun nfield, Warren I cou nty,'New Jersey, and LOUIS R. ALBERGER, a resident (of New York, New York eoun-ty,

New York, citizens of the'United States, have invented certain new and useful Improvements in Condenser Systems, fullyjdescribed in 'tliefoll'owing specification and the acconr' 1o panying drawings,for1ning a part of the same. a This. invention relates to condenser systerns of the class employing an elevatedinje'ctor,jet, or similar condnsen'the objectlof the invention being to pro'vide'a'constrnction by whichthe air and other uncondensable va- ;pors brought in with the steam'and condensing'water may be more efficiently removed from the condensing-chamber and delivered i by the air-pumpmhich is preferably employed with such condensers. I The-invention includes, broadly, the use of I a surface aircooler by which the air withdrawn from the condensing-chamber is cooled before entering theair-pump, this surface cooler preferably being placed on the pipe through which the condensing water passes "f toj'the condenser, so that the air is cooled by the,

condensing water. The surface cooler may,

f however, be otherwise placed and supplied 3o with other coolingliquid-within the invention, broadly considered.- The invention includes also in additio'n'to this broad invention cer- .tainfeatures of construction and combinations' of parts, all as fully described hereinaftegand specifically pointed out in the claims. i "-Fdiafull understanding of the invention 'a'd'etailed description of a construction .e'rnbodying all thefeatures of the same as apgiven in connection with the "accompanying drawings, forming a part of this-specification Fig; 2 is a partial View: looking tothe left'in Fig. 1, with the steam-pipe cut off; I Fig. 3 is I 9. central vertical section of the condenser and'air-cooler on a larger scale.

The condenser tail-pipe D' terminates in the hotawell E and preferably rests upon. the bottom of the hot-wel-l,as shown'in dotted lines',so as to support the condenserand its Pipe-iconnections The condensing water: is shown'ias' raised through the condensing-water-"pipeI) by the: circu'latingpump F, and the air is withdrawn from the condenser and delivered by the'air-pump G through" the connections hereinafter, described, the 'pumpsF Gt-being shown as separate steam-pumps, although it will be understood that any ot'her'su'i'table arrangement maybe used for pumping the condensing water andair. v i;

The condenser shown is, an injector-coa denser of the form shown in United StatesLetters Patent No. 227,342; but it will be understood that an injector condenser of anyother suitable form may be used or any sin1ilaa -;oo,n-. denser in which the condensip'g water and steam are brought into. contact and-where it is desirable to remove the airandbthkatfunconden'sable vapors .from the condensing-8o chamber. The injector-condenser shown and other forms'of injector, ejector, sipho n,orin duction condensers, to which may beapp'lied the general term F aspirator- ,condensers,, as

distinguished from other condensers, wilhop- 8 5 erate to carry on. with thewaten'a largepart of .the air; but especially implants of considerable size .the vain-pump is; preferablye nployed with such condensers and" important advantages are sec u-redthereby. 'Thus'the o.

amount of water required isreducedonly to that necessary for condensatioxnjeven under light e s as h c r nt o :11. p n off water haltnequired structed plant's. The'air-piinlp is not reguired" to removeall the air. from the] cofudensingchamber s of {such jcondensersfbut lo nly -that n,ot -r en1'oved-witl1 lthei'water, by the 'aspirat- 10o ing-condenser, sothat its'work is light. The present invention, however, is applicable 1n all cases in which an air-pump. is thus em ployed in connection with cond ensers,whether the air-pump be used to remove all the air and other unc'ondensable vaporsor not.

Referring now to the connections between the air-pump B and the condenser, to which connections, the present invention particularly relates, the condensing-chamber of coni denser A has in its upper part below the spraypipe an air-receiver 11, preferably placed centrally of the chamber and having a flaring or bell-shaped mouth opening downwardly, as shown, so, as to form a bell, which receiver or bell is connected by pipe 12 with the chamber through which the airfpasses from chamber 13 at one end of :the surface air-cooler H, placed Within t 'ndensing-water pipe-f0 so that the 00nd condensing-cha er c'ools the surfaces contact with which the air is cooled,.1wh1

surfaces are shown as formed by the t-llbfis lgl 5' 13 to chamber, 15 at the opposite end of the cooler, the condensing water passing through the spaces between these pipes. It will be seen that the surface air-cooler II forms asupplementary condensing-chamber arranged within the water-delivery pipe 0 and'cooled U more if this be not employed,'some watermay I be carried up the pipe 12 with the air, and thus pass to the air-pu mp G. The quantityof such waterwill be slight and may be neglected; but. to separatev this water thus carried through pipe 12 with the air we preferably use .baflle-plates 1 within the chamber 13, which aid in separating out the water,and we provide a drain-pipe 17 from chamber 13, whichpref,

erabiy connects with the lower part of the condensing-chamber or the upper part of the L tailpipe D, as shown, although, of course, this system or elsewhere.

pipe may run to any other suitable part of the I With the drain-pipe 17 preferably connects also a drain-pipe'18 from chamber 15, so that any'water that may ,possibly be carried over tochamber 15 will be removed thereby. By thus cooling the air on itsway from the condenser to the airpump we are enabled to secure a much more efficient removal of the air and other unconf densable vaporsfrom the condenser, increas- 'ing largely the eificiency of th elapparatus.

As this cooling of the air also increases its density and decreases its volume,a smaller air pump may be used, with a more eflicwntac:

n1; water on its way to he tion of the pump and less generation of heat by the compression and delivery of the air.

It; will be understood that our invention is notfto be limited to the apparatus shown, but that'other forms of apparatus are well adapted for the use of our invention and that the form and arrangement of the air-cooler con nections between the condenser and air-pump may also be varied widely without departing from the invention.
